Description: Adult males measure 19.6-20.8 mm SVL. A single adult female measured 21.7 mm SVL. Snout rounded to truncate in lateral view, with rounded canthus rostralis and sloping, concave loreal region. Nostril lies closer to the snout than the eye. Pupil vertical. Distinct round tympanum with weak supratympanic ridge. No vomerine teeth. Broad large tongue, with weak posterior notch. Chest glands are present without forming teats. Short bulky tibia. Fingers have dermal fringes and lack webbing. Tips of fingers are rounded and slightly expanded. Finger I shorter than Finger II. Heightened thenar tubercle not continuous to the thumb. Toes lack dermal fringes and have minimal, basal webbing. Both fingers and toes lack subarticular tubercles. Smooth dorsal and ventral skin, except that the lower region of the eyelid has indistinct tubercles. Males have neither vocal slits nor nuptial pads (Rowley and Cao 2009).

The dark brown dorsum may be uniform or mottled, or have an indistinct darker patch between the axillae. The venter is dark brownish pink with white speckles. Lighter indistinct vertical stripes on the tip of snout and under eyes. No interorbital bar is present. Upper lip has dark brown bars. Black stripe runs along the canthus rostralis through the eye to the supratympanic ridge and covering nearly the entire tympanum. Flank has 1-4 black blotches laterally and a large black blotch anterior to sacrum. Limbs may be barred with indistinct, diffuse bands. Elbow is lighter. Iris from gold to reddish copper (Rowley and Cao 2009).
